2-stage liquid ring vacuum pumps, widely used across for all general vacuum applications. These yacuum pumps can develop an ultimate vacuum of 30 mm hg absolute and are preferred for all processes where slightly higher vacuum is desired and could be quite helpful. Pumps are very simple in design with no balls or all supports used on control plates. These also offer economy in requirement of seal liquid, mechanical seals can be fitted externally on the shaft facilitating easy access without having to dismantle the pump completely, these pumps are ideal for combining, with ground level type steam jet ejectors for very low processing pressures.
